阪井養魚場是行程中最重要的一環，十月四及五日為他們的即賣會及拍賣會。相中的紅白的是購自阪井即賣會。Sakai Koi Farm is the most important distination in the journey. Their "Open sales" and "auction" were held on 4 & 5 Oct respectively. The Kohaku shown in the picture was bought from Open Sales.

由於即賣會的買家眾多，大會要抽籤決定選魚的先後次序，十分公平。Since there are scores of buyers in the Open Sales, a draw would be the most fair way to decide the priority.
